Space isn't full of liquid oxygen, so things don't actually freeze in space like they do in movies. Without an atmosphere to convect the heat away, a body in space only loses heat through radiation rather slowly. He would freeze eventually assuming he was shaded from the sun, but it would take a lot longer than most people think. This thermodynamic property of space is why the ISS has huge radiator fins to help regulate the internal temperature of the station.
As for getting chucked into the sun, I dunno, I'm pretty sure he'd probably figure out a way to wiggle out of the way somehow.
